How to Adjust Your Sleep Sensitivity (And Why You Should or Shouldn't)

If you feel like your Fitbit isn't properly recording when you fell asleep — versus when you're just lying on your couch watching TV — or that it fails to detect that you woke up in the middle of the night, you may want to adjust your the device. You can make your Fitbit more sensitive to your tossing and turning and other movements. Here's how.

1. From your Dashboard, navigate to your Account tab.

2. Scroll down and tap on Advanced Settings.

3. Tap on Sleep Sensitivity.

4. Tap on Sensitive if you want extra-detailed sleep tracking and records of nearly all of your movements. This can be helpful if you find that you keep waking up tired, Fitbit says. Normal may be a better setting if you sleep with a partner who tends to roll around in his or her sleep.
